SPECIFICATION forming part of Letters Patent No. 651,465,`dated June 12, 1900. Application filed March 10, 1900. Serial No. 8.208. (No model.)

To all whom t may concer/'11,:

Be it known that I, GEORGE E. LINr, a citizen of the United States, residingv at York, in the county offYork, State of Pennsylvania, have invented certain new and useful Improvements in Window Frames and Sashes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a window frame Aand sash, and particularly to a construction wherein a frictional contact with the frame is utilized to maintain the sash at different positions.

The invention has for one of its objects to provide an improved construction of sash adapted to cooperate with a frame having a beveled or inclined surface. Heretofore it has been old to bevel both the surface of the frame and the contacting face of the sash; but in these constructions therparts became wedged together when the sash was lowered and rendered the raising of the same difiicult, while'after it was raised there was no frictional contact to retain it in a raised position.

The present improvement is accomplished by means of a yielding incline upon one face of the sash adapted to travel upon the inclined way in the frame and normally held under sufficient tension to maintain the sash in any position.

A further object of the invention is to prowhich the parting strip or rail presses against one side of the sash at the mid-rail, while the opposite side of the' sash is held'under spring tension by means of .the yielding wedge' and strip.

Other objects and advantages of the invention will hereinafter appear in the following description ,and the novel features thereof will be particularly`pointed out in the appended claims.

In the drawings, Figure l is an elevation of the invention with parts in section. Fig. 2 is a vertical section thereof. Fig. 3 is a horizontal section on the line 3 3 of Fig. l. Fig. 4 is an enlarged detail section. Fig. 5 is a detail perspective of the lower end of the wedge-strip; and Figs. G, 7, and S are views similar to Figs. l, 2, and 3, respectively, showing the application of the invention to storm-sashes and screens.4

Like letters of reference indicate'like parts throughout the several figures of the drawings.

In the drawings the letter A indicates the Window-frame, which may be of any suitable size or eoniiguration and is provided with' the usual ways A', within which the sashesB are adapted to slide. The ways within the frame are beveled outwardly toward their lower portion,.as shown in Fig. l. In order to maintain a constant frictional contact between the sash and the frame for the purpose of maintaining the former at any de-y y sired elevation, awedge-strip C is provided, which is pivoted at its lower end by means of an angular pivot C", fitting loosely a socket of similar shape. This prevents any longitudinal orlateral movement of the strip C, but permits the same to incline outwardly, forming a bevel face to the sash, corresponding to the inclination of the way A upon the frame. This strip is held constantly under tension by means of a spring C2 and prevents the sash from becoming tightly jammed at the inclined lower portion of the frame. The strip furthermore holds the sash against any rattling or other movement, and when the sash is raised the strip will retain .the same in its position. In the present form of the invention it is only foundnecessary to apply this strip to one side of the sash; but it may be applied to both, if desired, and the ways for both of the sashes are similarly constructed.

' In order that the sash may be held by substantially-equal pressure upon opposite sides, and thus travel in a straight course, the parting-beads D are yieldingly mounted within the frame A for instance, loy..n;ieans of springs D behind the same-and these beads press against a face or shoulder B at the midrail of the sash, thus holding the same under yielding tension and preventing the frictional resistance which wouldbe causedby the strip C if the sash were forced by thesame against a rigid face at the opposite side of the frame.

IOO

The shoulders B upon the sashes are located at opposite sides by forming the mid-rail with an inclined face, and one of the parting-beads D bears against each of the sashes at the meeting-rail. It may be stated that the beads D are provided with springs Dl at suitable points throughout their length in order ehat they may be pressed outward with an equal pressure, and for the purpose of holding the bead in position at the end of the sash farthest from the meeting-rail a pin or lug B2 is provided and travels in contact with the face ot' the bead D. lt is also proposed to apply the yielding wedge or strip C to other than the window-sashes proper, as shown at B. For instance, as illustrated in Figs. 6, 7, and S, storm-sashes E may be located within the window-frame and provided with spring strips or wedges E', similar to those hereinbefore described, which strips are adapted to ride upon suitable ribs or ways formed in the frame A, and these storm-sashes are independently mounted, so that they may be freely moved when access is desired tothe main window-sashes B. The holding strips or beads D and the construction of mid-rail with the shoulder B are provided in these modifications of the invention. lf desired, a screen F may be removably located upon the outer portion of the window-frame, as shown in Figs. 6, Y7, and S, and may be mounted upon strips or beads FC The screenframe F is provided upon opposite sides with spring-strips F2, by means of which the frame may be placed in position and the joint between the strip and the frame proper may be suitably covered by means of an overlapping flap F3 of any suitable material. It will be obvious from the construction shown that the different parts of the window may be removed whenever found desirable-for instance, the storm sashes removed during the warmer weather or the screens during the winter season. It will be obvious that the sashcs may be easily operated and held at their adjustments without rattling by the construction described.

From the foregoing description of the construction of the invention the operation will be clearly understood, and it need only be stated that the use of the spring wedge or strip pivotally mounted at its lower end p-revents the jamming and wedging of the window when in its lowered position, which is common with those constructions embodying an inclined wayin the traine. This construction of way, however, is desirable, as when the window islowered itis tightly held against rattling or other movement due to the pressure of the air thereon, and by overcoming the difficulties heretofore existing a very desirable construction of sash is provided. Furthermore, in the construction heretofore used when the window is raised to the wider portion of the inclined way there is no holding means by which it may be retained in position, and it must be secured by some independent device. The spring strip or wedge herein used exerts such a constant tension on the way as to hold the window at any desired position, and `this action is materially improved by the use of the spring l, bearing against the sash to cause the same to travel in a straight path. It may here be stated that the well-known construction of spring-strip at the side of a sash yieldingly held at both ends is not adapted for use in my invention, as it is very difficult to cause the same to assume the inclined position attained by the use of the pivot and single spring herein illustrated.

It will be obvious that changes can be made in the details of construction and operation without departing from the spirit of the invention as defined by the appended claims.

Having described my invention, what l claim isl.

5. In a frame and sash, the combination of a frame having an inclined Way, of a sash provided with a strip pivoted at its lower portion in said sash, a spring above said pivot to force said strip against said way, a yielding bead bearing against a shoulder upon said sash upon the opposite side from said strip, and a lug carried by said sash'and bearing against said bead; substantially as specified.
